2. WHAT IS HISTORY?
Why Study History?
People who study history are called historians. Historians
study causes and effects of historical events. A cause is a
reason that something happened. An effect is what
happened because of an event. Historians try to figure out
why things happened. They use their understanding to
think about how those things make a difference today.
Learning about the past helps us understand the
present. It helps us decide what to do in the future.
Knowing what went wrong in the past can help us make
better decisions today when we face similar choices

3. era
 Measuring Time
A group of 10 years is called a decade. A group of 100
years is called a century. Ten centuries grouped together is
called a millennium, which is a period of 1,000 years.
A period of several centuries is sometimes called an era .
The earliest era is called prehistory. Prehistory is the time
before people invented writing. The next period is called
Ancient History. Then come the Middle Ages. Sometimes
the Middle Ages are called the medieval period. The era
after the Middle Ages is Modern History. We live in the era
of Modern History.
Decade=10 years
Century= 100 years
Millennium=1,000 years
Era=Several centuries

4. Why do we use calendars?
 To keep track of days and months, we use a calendar.
Some cultures use calendars that are different from ours.
Some calendars are arranged according to nature or the
position of the moon.
Our modern calendar is based on one that started in
ancient Rome. Julius Caesar invented it. We call it the
Julian calendar. It started counting years from the time
that Rome began. It was created with 365 days each year
and one extra day every fourth year, called a leap year.
However, there was a problem with the Julian calendar. It
lost several minutes each year. That meant there was one
day lost every 128 years. It needed to be fixed.

5. Calendars
 Pope Gregory XIII decided to create a new calendar.
 Pope Gregory changed the starting date of his calendar. He began
counting years on his calendar from what he thought was the birth
of Jesus. He also fixed the mistake from the Julian calendar. Pope
Gregory included leap years in his calendar, too. We call Pope
Gregory’s calendar the Gregorian calendar. Although there are
other calendars, most of the world uses the Gregorian calendar
today.

8. archaeology
 Archaeology is the study of the past by
looking at what people left behind. An
archaeologist digs in the earth for artifacts.

9. artifact
 An artifact is an object made by people. Tools,
pottery, weapons, and jewelry are artifacts. They
help
archaeologists learn what life was like in the
past.

10. paleontology
 Paleontology studies prehistoric times.
Paleontologists study fossils.

11. fossil
 Fossils are the remains of plant and animal
life that have been preserved from an earlier
time.

12. anthropology
 Anthropology is the study of human
culture.
Anthropologists study artifacts and fossils, too.
They look for clues about what people valued
and believed.

13. species
 A paleontologist named Donald Johanson made an
important discovery in Africa in 1974. He found the
skeleton of an early human who lived more than
3.2million
years ago. He called the skeleton Lucy. Lucy belonged
to a
different species of early human. A species is a group of
animals or humans. The members of a species are alike
in
some way. Lucy is the oldest human species that
scientists
have ever found. Lucy can help us learn more about
how
humans developed.

15. evidence
 What Is the Evidence?
 Historians look at evidence to find out about
the past.
 Evidence is proof that something is true.
Evidence might be an object, such as a
soldier’s uniform or a scrap of pottery.
 Evidence might also be a document or book
that was written during a historical event.

16. Primary source
 A primary source is a kind of evidence. Primary
sources are created by people who saw or were part of an
event.
Examples:
A. Letters
B diaries
C. Tools
D. Clothing
Historians use primary sources to learn what people were thinking at
the time of the event.
Primary sources can help historians explain events that happened long
ago.

17. Secondary source
 A secondary source is also evidence. Secondary
sources are created after an event. They are
created by people who were not part of the event.
Examples:
1. Textbooks
2. Encyclopedia
Secondary sources can give a broad
view of historical events or people.
However, new
information can only come from primary sources.

18. Point of view
 Historians analyze the information in their
sources. They look for reasons that the source
was created. Then historians decide if the
source is reliable when it comes to its facts.
Each source was written with a particular
point of view, or attitude about people or life.

19. bias
 The author of a source uses his or her point of
view to decide what to include in the
document. Sometimes a point of view is based
on feelings and not on facts. A judgment based
only on feelings is called a bias. Sources with
a bias cannot
always be trusted to be factual or true.

20. SOURCES THAT HISTORIANS
USE
 Written at the time
of the event.
 Eyewitness to
history
 Reliable source for
historians
 Includes letters,
diaries, tools, and
clothing
 Written after an
event
 Author did not
witness the event
 Contains facts about
an event
 Includes textbooks
and encyclopedias
PRIMARY SOURCES Secondary Sources

21. scholarly
 Historians interpret information from primary sources to make
inferences. Making an inference means choosing the most likely
explanation for the facts. Sometimes the inference is simple. When
you see someone with a wet umbrella, you can make the inference
that it is raining. Making inferences about historical events is not so
easy.
 To make an inference, historians start with primary sources. They
use sources they already know are trustworthy. Next, they read
secondary sources. They think about the different points of view.
Finally, they make an inference to explain what happened.
 Many historians write articles about their inferences. Most articles
are published in scholarly journals, or magazines. Scholarly
magazines are concerned with learning. Usually, other historians
read the articles to make sure the facts are correct. They decide
whether they agree with the inferences in the article. Historians
must be careful to make inferences based on facts. They do not
want to show a bias in their writing.

23. conclusion
 A conclusion is a final decision that is reached by
reasoning. It is like an inference.
 Historians draw conclusions about events of the past.
They look for facts and evidence in their sources.
 Then, they use reasoning to draw a conclusion.
Sometimes historians disagree in their conclusions.
 For example, some historians say that Genghis Khan was
a brutal warrior. They tell how he would destroy cities and
kill people when he came to a new land. Other historians
disagree. They say that Genghis Khan was a good ruler.
His empire had a time of peace. Traders were safe to trade
goods. People were protected by good laws.

24. Which conclusion is correct?
Examine primary sources
Use already-known facts
Read secondary sources
Use facts to make an inference or draw a
conclusion
Write article about inference or conclusion

25. Planning Your Project
 The first step in researching a history topic is to choose a topic. Your topic should not be too broad or too narrow.
To test your topic, look it up in an encyclopedia. If there is no entry for your topic, it may be too small. If there are
many entries, or a very long entry, the topic may be too large. After you choose a topic, decide what you want to
learn about. Create six questions to help you find out who, what, when, where, why, and how. Write each question
on a separate note card. As you find the information that answers each question, write it on the card.
 The next step is to collect your research materials. Start with an encyclopedia. Then visit the library to find a book
about your subject. The sources must be nonfiction. Finally, look for articles on the Internet. Look at each book
and article to make sure it is trustworthy. Look for statements that are opinions. This can help you determine
whether the source is biased or untrustworthy. A good source will be full of facts. Remember, a fact is something
that can be proven by evidence. An opinion is an attitude toward something. It cannot be proven true or false.
 As you collect information about your topic, write a short phrase on your note card to help you remember the
facts. On the back of each card, make notes about the books where you found the information.
Choose a topic
Collect sources
Decide if each source can be trusted

26. credentials
 Looking for information on the Internet is quick. However, finding sources you can trust can be tricky. Many
articles on Web sites do not name the author. The reader cannot tell whether the person who wrote it is an expert
on the subject. A trustworthy article will include the author’s name and credentials. Credentials are evidence that
someone is an expert.
 The homepage of the Web site can give more clues about the trustworthiness of the article. If the article is on the
Web site of a university, government office, or museum, it is probably reliable. A good clue to find out about a Web
site is its online address, or URL.
 Look at the end of the URL.
 gov is a government site. This site probably has reliable information that is usually up to date.
 .edu is the site of a school or college. Most .edu sites pride themselves on accuracy. However, some
documents may contain opinions as well as facts.
 .org is a nonprofit organizations usually end their URLs in These sites may be very accurate. However, they
often contain opinions.
 You have now collected information about your topic. You have answered the questions on your cards. Now you
must sort your information into categories. Internet Tips
If you answer NO to any of the questions
below, the Web site is probably not a good
source.
• Can you tell who wrote the article?
• Can you easily find out who is
responsible for the Web site?
• Has the page been updated recently?
• Does the writing show a bias toward one
point of view?

27. plagiarize
 Putting all the facts of your research together can
be hard work. You should keep in mind some
important guidelines for writing about history.
 One problem to watch out for when you are
writing a
research paper is plagiarism. Plagiarism happens
when a
writer uses the exact words or ideas from another
person
without giving credit. Readers are wrongly led to
believe
